Creating a Confident Security Posture
Case study: Aerco Limited
Background
Aerco Limited is a leading UK stockist and distributor of electrical components. Offering specialised products to manufacturers in the aerospace, defence, medical, industrial, rail and transportation markets.
With a growing digital estate underpinning both operational delivery and corporate functions, Aerco places strong emphasis on resilience, reliability, and demonstrable cybersecurity maturity.
Challenges
As part of a long-term commitment to cyber resilience, Aerco recognised that traditional, point-in- time security testing did not provide the level of assurance required by modern risk and governance expectations.
Security leadership wanted confidence that cyber risk was being actively reduced throughout the year, not simply identified annually and revisited months later.
Key challenges included:
- Maintaining confidence as systems and services evolved
- Demonstrating meaningful risk reduction to senior stakeholders
- Ensuring security improvements were sustained over time
- Translating technical findings into business-relevant decisions
- Moving away from a transactional supplier model towards a trusted security partner
Project Approach
Aerco engaged Samurai Digital Security Ltd to provide continuity, clarity, and measurable improvement rather than isolated assessments. The focus of the engagement was not individual reports, but a structured, repeatable assurance programme that allowed Aerco to:
- Maintain ongoing visibility of risk as changes occurred
- Track remediation progress and improvement over time
- Receive consistent, contextual guidance aligned to real-world threat and business impact
- Build internal confidence and capability rather than dependency
Samurai acted as an extension of Aerco’s team, ensuring security outcomes were clearly understood, prioritised, and achievable.
Outcomes & Benefits
By adopting a continuous assurance model, Aerco achieved tangible improvements across both security posture and organisational confidence:
- Sustained reduction in cyber risk, rather than periodic snapshots
- Faster, more effective remediation driven by clear prioritisation and context
- Improved visibility and governance, enabling progress to be evidenced to senior
stakeholders - Stronger internal understanding of cyber risk, supporting better decision-making
- A proactive, trusted partnership, replacing one-off testing with long-term assurance
This approach enabled Aerco to move decisively from reactive testing to proactive risk management.
Business Impact
The engagement with Samurai provided Aerco with confidence that cyber risk was being managed as an ongoing business concern, not a compliance exercise.
Security assurance became measurable, repeatable, and aligned with organisational priorities, supporting both operational resilience and long-term strategic planning.
Testimonial
“Samurai have been an outstanding partner over the last two years. Their approach goes far beyond delivering reports, the focus has always been on clarity, practical outcomes, and genuine risk reduction.
The vulnerability management platform has transformed how we track progress, and the guidance we receive is consistently clear and actionable. Most importantly, the relationship has been collaborative and supportive throughout. We now have real confidence in our security posture and are delighted to be committing to a long-term engagement.”
